Solar Wire Size..??? Fuses on panels...??

I used 10/3 out door cable to connect panels to combiner box with circuit breakers. Longest run was around 6 feet. From the combiner to the controller was a long run maybe 45 feet or so and used the same 10/3 cable to the controller a Morningstar ts 45 a PWM unit. I went through all of this set up with the Altestore before I did it and bought the controller and combiner box from them. 10/3 was all I could find where I live from the electrical supply house. Last week was the trial run, dry camping on the beach for 7 days. Never used the generator once! 4 112 watt panels and all of this goes into tow Trojan t125's. I utilized a Bogart engineering battery monitor to see how I was doing. Charging started as soon as 8 am and went all the way to 4 pm ish before the sun got to low. The batteries charged all the way except for one day a little hazy. Two adults and two college kids charging laptops, phones ipads, water pump for dishes showers, TV's and lights, and it was successful. I have two more panels that I am going to install shortly and perhaps two more Trojans. Most of the dry campers have a 4 battery set up.
